airGateway is the easiest way to add indoor Wi-Fi capability to airMAX CPE deployments. airGateway provides 802.11 b/g/n Wi-Fi and interlocks with existing PoE adapters, so there is a single power source for the CPE and airGateway devices.
Works perfectly with Ubiquiti NanoBeam, Nanobridge and NanoStations
